NEWS-PROJECTIN'G MACHINE.

Application led July 16,

This invention relates in general to machines for projecting news andquotations as' they are printed by a' ticker and more particularly to aprojecting machine 1n which the news is printed transversely of the tapein al series 'of rows, and in which thetape 1s advanced aline space atatime.

Among the objects ofthe present 1nven tion, it is aimed to provide acombination of projecting machine and ticker mechanlsm/ in which theprinted matter lis printed transversely of the tape and whereby theprinted matter may be projected to a screen chsposed above the tickermechanism.

Specifically the invention provides in. combination a lamp housinghaving a horizontal transparent support for thetape, a horizontal guidefor the tape extending above the top of the lamp housing and spaced fromthe lamp housing by an -air chamber, and a ticker mechanism `disposed toone side of the lamp housing adjacent to the-.horizontal transparentsupport, whereby images of the printed matter on the tape will beprojected upwardly through a projecting lens, into a v deflecting mirrorand from the deiecting mirror to a vertically extending screen disposedabove the ticker mechanism.

Among the objects of the present inven- GORPORATION 0F NEW YORK. i

1926. Serial No. 122,814.

on the tape in lines extending transversely of the same.` At the upperend of thehousing 5, there is formed an opening 9A through which thetape T passes after' leaving the t1cker.8.l lThetape T is preferablytransparent or translucent, ordinary ticker tappe however beinggenerally sufficiently translucent to give fairly good results. Afterleaving the opening 9, theA tape passes over the shield 10 of thehousing 5. -to and under the bar 11 supported. by the bracket l2 on theupper rightv hand end of the lens casing 13. The lenscasng 13 extendsfrom the right Aend of the lamp housing 14 which is supported on theplatform l to the left of the housing 5. In the lamp housing and securedto the rear wall lthereof, there is formed the bracket 16 on therighthand end of which is mounted the lamp 17 and to the left .of whichis'mountedfthe-.reflector `18. Secured to the inside of thefwall 19ofthe lamp housing, there is. provided the 'condensing lens member 20lwhich extends through the opening 21 formed in the Wall tor or mirror2,1 inclined at an angle of about 45to the wall 19. Thel upper wallmember 22 of the lens-housing 13 is protion, itis also aimed to providean improved A`vided with a transparent tape v'support 23 rewindmechanism for ticker tape in which the printed matter extendstransversely of the same.

"These and other features, capabilities and the subjoined detaildescription of .one embodiment thereof illustrated in the accompanyingdrawings, in which Figure' 1 Ashows the various portions of theapparatus assembled in section;

Fig. 2 is a sectionsubstantially on the line 2-2 of Fig. 1; and

Fig. 3"is a plan view of and ticker. v

As shown in Fig. 1, a platfrom 1 is provided spaced from the platform 2by the end-members 3 and 4. lOn the right hand end .of the platform 1there is provided a housing 5 having a platform 6 beneath which` thereis supported in the usual way a r 1l of tape 7. On the platform ismountev the ticker '8. The ticker 8 is of standard construction such asthe .Dow-Jones ticker in which the tape is advanced one line space.. lata time and the printed matter is impressed the lamp housing composed ofglass beneath which there is lens memberA 25 which is secured inposition by a bracket 26 secured to the lens housing 13. The wall member22 extends from the lens j housing 13` above the lamp housing' 14 and'isspaced from the upper wall member- 27 of the lamp housing to form anlair chamber between the walll member .22 and the wall member 27 so. thatthe support 22may be protected by this air chamber from the heatcreated` in the lamp housing 14. The left hand end of the Wall member 22or tape support is curved downwardly, as shown at 28;

To the left of the lamp housing 14 the platform 1 is-provided with anopening 29,` the tape passing from under the bar 11 over the glasssupport 23 to the guide 22 and then over the curved portion 28 downthrough the opening 29 to the take-up reel 30. LThe take-up reel has ashaft 31 provided with an axially extending recess 32 and a disc 33 atthe inner end of the shaft 31. The shaft 31 is mounted'on the bearingbracket 34 and there is secured a worm wheel 39 in mesh with the worm 40on the shaft 38. On the shaft 37 there is also secured asheave 41 .whichis connected to the sheave 35 by the spring belt 42. The shaft 38 isconnected to the shaft 43 of the motor'44 by the -lexi- .ble connection45. The tape T is initially lsecured to the shaft 31 by being threadedthrough the opening 32. It will be seen from the foregoing that themotor 44 through the.-

worm 40 will drive the worm wheel 39 in turn to drive the sheave 41,which sheave 41 by means of the spring belt 42 will frictionally drivethe sheave 35 in turn to rotate the shaft 31 and thereby wind up thetape T. Above the projecting lens 25, there is provided a defleetor -ormirror 46, in the present instance secured by the bracket 47 to theceiling member 48. To the right of the mirror 46, there is positionedthe screen 47 which is also secured to the ceiling. member 48.

I,In the operation of this,setup, the tape l will pass from the roll 7through the ticker 8 in which the lines of printed matter will be.impressed on the tape and from the ticker 8, the tape T will passthrough the opening 9 over the shield 10 to the bar 11,

under the bar 11 and over the glass support 23 to the guide 22 .and fromthe guide 22, over the curved portion 28 lto the wind-up reel 33.` Sincethe tape T rests during the printing of a line, provision ,must be madefor permitting the take-up or wind-up reel to rest at the same time. Tothis end, the spring belt 42 is*l provided which is -suticientlyyieldable to slip when the tape T is arrested by the ticker 8 but willhave suiiition with atranslueent ticker tape having vthe printed matterreading transversely cient frictional engagement with the sheaves y35and 41 positively to'v rotate the shaft 31 as soon as the tickeradvances the tapeT in order to maintain thetape smooth on the 'support23 and at thesamel time positively wind it `on the shaft 31. In theprojection of the' printed characters, it will be seen 'that thelightrfrom theglamp 17 passes through thecondensing 1ens'20` to themirror 21 and .'fthen'through the lens 24 and glass support 55" 23,`through the tape positioned thereon,

whereupon the images of the characters on the tape will be projectedthrough the projecting lens 25 to the mirror 46' and then to the screen49. In order that the rows of printed matter will appear printed side up.and reading from left to right, the printed surface of the tape Tlwill.face downward when it passes over the glass plate 23,1there?.

upon the images ofthe. characters-'fon the tape T v vlll be projectedthrough the glass plate 23 inverted from left to right. the

images are received by the projecting lens 25, they will be invertedupsidedownside and still remain inverted from left to right.

As the images are then received by the mirror 4G, they will be set upinto proper position to be deflected onto the screen 47 v.reading intheir proper order from left to right.

In order to form lateral guides forthe tape when passing over the shield22, the

ybent ledges 50 and 51 are secured to the shield 22 and extend upwardlytherefrom and inwardly tow-ard one another, as shown in Fig. 3, theedges of the tape T moving Voverthe shield 22 and under the ledges 50p.

The walls 15 and 27 of.

plates to deflect the heated air leaving the housing 14 through theopening 52 in a downward directionso that such heated air will not passup through the wall 27 'and guide 26. The wall 14 has a member 53 thatextends horizontally' outward from the lower end of the y opening 52 andthen verti'v l cally upward. The wall 27 has two deflecting balileplates 54 and 55, the bailleplate 54 extendingto the left from the wall27 to the lower end of the'curved portion 28 of the plate 13, and thebaille plate 55 errtending vdown to the right of the vertical portion ofthe member 53 so that the vertical portion 53 extends upwardly into thespace between the battle plates 54and 55.

It is obvious that various changes and modifications may be made to thedetails of construction without departing from the general spirit of theinvention as set forth in the appended claims.
